Understanding soil erosion responses to cropland expansion/shrinking plays a crucial role in regional agriculture sustainability development drylands. We selected Inner Mongolia, typical water resource constraints region with acute expansion, as the study area China. Spatial evolution and its impact on wind-driven were investigated help of field sampling data, remotely sensed retrieved revised ...

Precise knowledge of crop water consumption is essential to better manage agricultural use, particularly in regions where most countries struggle with increasing and food insecurity. Approaches such as cloud computing remote sensing (RS) have facilitated access, process, visualization big geospatial data map monitor requirements. To find the reliable Vegetation Index (VI)-based evapotranspirati...

abstract shortage and improper distribution of rainfall in tea growing period are important growth limiting factors in tea fields in northern part of iran. if there is not any other limited factors, supplemental irrigation by sprinkler can increase tea yield. this study was carried out in order to investigate the optimum sprinkler irrigation interval on yield and water use efficiency of tea. th...

abstract due to limited water resources and occurrence of recent droughts, the use of new management and planning methods for optimal irrigation scheduling of agricultural crops is inevitable. present of appropriate mathematical and dynamic relationship between yield, evapotranspiration and water use efficiency parameters is the first and most important step in the optimal management of irrigat...

this research was conducted at the shahrood agricultural research center in 1382 and 1383 to study the effect of alternate furrow irrigation on potato yield and its economic evaluation. the experimental design was a randomize complete block design and the treatments were: every furrow irrigation (efi), fixed alternate furrow irrigation (fafi), variable alternate furrow irrigation (vafi), fixed ...

water use productivity is one of the most important factors in scientific agriculture. it is equal to 0. 7 kg of production per cubic meter of irrigation water (kg/m3) in iran which is very low in comparison with advanced countries (1 to 2 kg/m3). current research studies temporal and spatialchanges of water use productivity in hamedan province in iran using geographic information system (gis),...

Abstract The divergence between agricultural water use and the annual supply of resources (water gap) has been increasing for decades. forecast is that this gap will continue to widen, compromising security a large share global population. On one hand, increase in demand attributed an ever-growing population that, addition, adopting high-water consumption per capita lifestyle (e.g., meat-rich d...

Biological soil crusts (BSCs) are thin microbiological vegetation layers that naturally develop in unfavorable higher plant conditions (i.e., low precipitation rates and high temperatures) global drylands. They consist of poikilohydric organisms capable adjusting their metabolic activities depending on the water availability. However, they, with them, ecosystem functions, endangered by climate ...

land use optimization is one of the suitable methods for soil conservation. the present research with objective of land use optimization for soil erosion minimization and pure income maximization was conducted in the part of taleghan watershed which comprises 80427.23 ha in area. to achieve this propose, area, erosion rate and net income value of each land uses according to requiring standards ...
